There are many things that annoy people on blogs but here are just some of them:
Colour
Some blogs use crazy colours. Making their background white and then having light gray letters. That does not make sense. Colours can put people off your blog.
Ads
We all need to make or have money but just blend your ads in your blog. Its both annoying when they stand out to much.
Flash
Flash sucks. Anything that moves while you are trying to read something sucks.
Loading time
Your blog should at least load before the end of earth.
